摘要： The display device using a transparent-scattering type liquid crystal element has such a structure that the light quantity to an observer is controlled as possible when a black image (transparent state) is provided, and a high efficiency of light is maintained when a white image (scattering state) is provided. A prism array (12) is disposed at the back surface of the transparent-scattering type display element so that a sawteeth-like surface of the prism array (12) faces the display element (11) and a light absorber (13) is disposed at the back surface of the prism array. A light source (14) can be disposed at a side face of the prism array (12), with a reflector (16) at the opposite side of the light source (14) with respect to the prism array (12). A display device having high contrast ratio is obtainable.

摘要： A reflection type color liquid crystal display apparatus comprising a polarizing plate (1) having an absorbing axis (18), a birefringent plate (3), a liquid crystal layer (6) and reflection layer (8) wherein the absorbing axis (18), a first orientation (14), a second orientation (15), a first optical anisotropic axis (16) and a second anisotropic axis (17) are set so as to form predetermined crossing angles ( theta 1, theta 2, theta 3, theta 4) and selected voltage values of at least three values are applied to the liquid crystal layer (6) from a multiplex driving circuit (10). Without using a color filter, a very bright chromatic color (white or black) is displayed at the time of an OFF waveform even in multiplex driving, and development of colors of very bright red, blue and green can be obtained with a selection voltage or an intermediate voltage between the selection voltage and a non-selection voltage.
